It is important to understand that fuses serve as a barrier that absorbs the shock of a short circuit, protecting expensive wiring and electronic control units from failure.
In this article we will analyze in detail the location of the blocks, decipher the markings and give clear instructions for checking. You will learn how to properly replace a blown element and what to do if the new fuse burns out immediately. This is fundamental knowledge for any car owner who wants to maintain his Nissan Almera in good condition.
Location of protection units in the car interior
On Nissan Almera 2006, the main fuse box, responsible for the internal electronics, is hidden from prying eyes. It is located on the left side of the dashboard, directly behind the decorative plastic cover that covers the driver's footwell. To access it, you need to open the door and feel the latches on the panel.
Removing the cover does not require the use of special tools. It is enough to carefully pull it towards you, overcoming the resistance of the plastic clips. After removing the cover you will see rows of fuses and relays. There is often a simplified diagram on the inside of the cover itself, but it may be erased or not contain complete information about all the elements.
Please note that next to the block there is often another small block with a relay, which is responsible for controlling power consumers. Location elements may vary slightly depending on the configuration and market in which the car was assembled, but the general scheme remains unchanged.
⚠️ Attention: Before starting any work on removing or checking elements, be sure to disconnect the negative terminal of the battery to avoid a short circuit if you accidentally touch metal tools.
Use special tweezers, which are usually kept in a block, or good quality tweezers to remove the elements. Do not try to pull out the fuse with your fingers, as this may damage the contacts in the connector.
Fuse box in the engine compartment
The second, and often more important, unit is located under the hood of the car. It is located on the right side of the engine compartment, closer to the mudguard, and is closed with a thick black cover. This unit is responsible for powering high-voltage consumers, such as headlights, windshield wipers, fuel injection system and cooling fan motor.
The engine compartment cover is opened by snapping off the metal or plastic clips around the perimeter. Inside you will find not only standard pin fuses, but also larger elements designed for high currents, as well as power relays. The markings on the outside of the lid often duplicate the purpose of the elements inside.
This block also contains main fuses, responsible for supplying power to the main components of the car. Their burnout often leads to complete failure of the ignition system or generator. When checking this unit, be extremely careful, as there are high voltage wires coming from the battery.
- ✅ Regularly check the condition of the contacts in the engine compartment, as moisture and dirt can lead to oxidation.
- ✅ Use only fuses with strictly corresponding color markings and ratings.
- ✅ Monitor the integrity of the rubber seals of the lid to prevent water from getting inside the unit.
If you find that a fuse has blown, but immediately after replacing it fails again, this is a sign of a serious problem in the circuit. In this case, further operation without diagnostics is strictly prohibited.
Table of denominations and purpose of elements
To quickly diagnose, you need to understand which fuse is responsible for what. Below is a table compiled from factory data for Nissan Almera 2006. It will help you quickly find the element you need without having to go through the entire block.
| Denomination (A) | Color | Purpose | Location |
|---|---|---|---|
| 10 A | Red | Front dimensions, instrument lighting | Salon |
| 15 A | Blue | Electric windows, cigarette lighter | Salon |
| 20 A | Yellow | Heater fan, audio system | Salon |
| 30 A | Green | Wiper motor | Under the hood |
| 40 A | Yellow | Alternator main circuit, ABS | Under the hood |
Please note that the ampere rating strictly corresponds to the color of the fuse body. This allows you to visually assess the compliance of the element with its intended purpose even without special instruments. Color coding is an international standard adopted at Nissan factories.
Sometimes the fuse body may have markings on it that differ from the standard color scheme. In such cases, always refer to the denomination indicated by the numbers on the top of the element. Replacing a fuse with an element with a higher rating is unacceptable and may lead to a fire in the wiring.

Method for checking and replacing fuses
Checking the fuse is a simple procedure that can be done either visually or using a multimeter. The visual method is suitable for most cases: just remove the element and look at the metal jumper inside the plastic case. If the jumper is torn or melted, the element must be replaced.
For more accurate diagnostics, use a multimeter switched to dial mode. Attach the probes to the contact legs of the fuse. If the device beeps or shows zero resistance, the fuse is good. The absence of a signal indicates an open circuit.
When replacing, always use an element with the exact same rating. If you don't find the fuse you need, you can temporarily use an element with a lower rating, but not a higher one. Installing a fuse with an excessive current will act as a “bug” and will not protect the circuit in an emergency.
- ✅ Remove the fuse only with special tweezers or pliers to avoid damaging the contacts.
- ✅ Before installing a new element, make sure there is no moisture or dirt in the nest.
- ✅ After replacement, check the operation of the corresponding unit before closing the unit cover.
If the problem persists after replacing the fuse, the problem may not be in the element itself, but in the relay or wiring. In this case, a more in-depth diagnosis will be required using the electrical circuit diagram.
⚠️ Warning: Never try to short-circuit the contacts of a blown fuse with foil or a paper clip. This will instantly lead to overheating of the wiring and a possible fire in the cabin.
☑️ Check before replacement
Frequent malfunctions and their causes
On Nissan Almera 2006 owners often encounter blown cigarette lighter fuses. This occurs due to the connection of powerful chargers or car refrigerators that exceed the permissible load of the circuit. The cause may also be a short circuit in the cigarette lighter connector itself due to foreign objects.
Another common problem is the failure of power windows. In this case, the relay in the engine compartment often fails, and not the fuse itself. The relay may stick due to worn contacts or moisture, which leads to overheating and subsequent tripping of the protection.
Sometimes the fuses responsible for the ignition system or fuel pump blow out. This is a serious problem and may indicate a short circuit in the motor windings or damaged wire insulation. Diagnostics Such faults require professional equipment and skills.
It's important to note that continually blowing the same fuse is a symptom, not a disease. Ignoring this fact and constantly replacing elements only masks the real problem, which can lead to costly wiring repairs in the future.
Why does the cigarette lighter fuse blow?
Most often, the reason is the use of cheap chargers with high current consumption or deformation of the contact group inside the cigarette lighter socket, which causes a short circuit to the housing.
Working with relays and power elements
In addition to fuses, in blocks Nissan Almera There are relays that control the switching on of powerful consumers. Relays are electromagnetic switches that can fail over time. The main signs of a faulty relay are clicks when turned on, failure of the unit to operate, or spontaneous activation.
To test a relay, the method of replacing it with a known-good element from another unit with similar characteristics is often used. For example, you can swap the positions of the fan relay and the windshield wiper relay if they have the same markings. If the problem moves with the relay, then it is faulty.
Power relays in the engine compartment are often exposed to high temperatures and vibrations. This leads to the destruction of internal soldering or oxidation of contacts. Regularly cleaning the contacts and checking that the relays are securely fastened will help extend their service life.
- ✅ Always check the relay markings before replacing, as the relay may be the same, but the characteristics are different.
- ✅ When installing a new relay, make sure that it sits tightly in the socket and has reliable contact.
- ✅ Use dielectric contact grease when installing the relay in a humid environment.
If you are not confident in your abilities when working with relays, it is better to contact a professional auto electrician. Incorrect installation or connection may result in burnout of the ECM or ABS.
If the relay clicks, but the device does not work, most likely the problem is in the relay itself or in the power contacts. Try gently tapping the relay body - sometimes this helps restore contact temporarily.
Tips for electrical prevention and care
To avoid frequent electrical problems, it is necessary to carry out regular preventive inspections. Clean the fuse boxes from dust and dirt using compressed air or a soft brush. Make sure the unit covers are tightly closed and have intact seals.
Do not overload the vehicle network with additional equipment. Installing powerful radios, subwoofers or LED lamps without using separate fuses and relays can lead to burnout of standard elements. Always connect additional equipment through a separate fuse coming directly from the battery.
Keep a spare set of fuses and relays in the glove compartment or glove box. This will allow you to quickly fix the problem on the road. The set should include elements with the most common ratings: 10, 15, 20, 30 amperes.
Remember that the electrical system Nissan Almera 2006 is quite reliable if used correctly. Timely replacement of worn-out elements and compliance with the rules for connecting additional devices guarantee long and trouble-free operation of the vehicle.
Regularly checking and cleaning fuse boxes from dust and moisture is the easiest way to prevent sudden electrical failures while on the road.
